grrrr … 😦
Every once in a while I try to edit video in the .MTS format on my MacBook with the built-in free software iMovie.
Sometimes it works. Most times not.
• on a Mac you can watch .MTS video using free, open source VLC software
• if you MUST edit, an excellent way to convert MTS files for Mac is using free, open source Handbrake software
details – Handbrake can convert MTS files for Mac
• if you MUST edit (and have money) higher end software like Final Cut does import .MTS
… first try using a cable directly to the camera, rather than simply the SD card via a card reader. That sometimes works.
If you’re an Apple person, best not purchase any camera that saves video in the MTS format. Check.
Lastly, I’ve ended up with some SD cards with old video files that cannot be deleted. For those it’s best simply to reformat using Apple Disk Utilities ERASE. The best format in 2012 seems to be exFAT — readable by almost all modern Windoze and Mac devices.
External Hard Drives should be formatted in exFAT, as well.
